1. What Flomaxtra XL is and what it is used for
What is Flomaxtra XL
Flomaxtra XL contains the active substance tamsulosin
hydrochloride. It acts by relaxing the muscles in the prostate
and urethra (the tube that carries urine to the outside), and lets
urine pass more readily through the urethra and aids urination.

Like all medicines, this medicine can cause side effects,
although not everybody gets them.

Please inform your doctor that you are on Flomaxtra XL before
any operation or dental procedure as there is a potential that
your medicine may interfere with the effects of the anaesthetic.
Pregnancy, breast-feeding and fertility
Flomaxtra XL is not indicated for use in women.
In men, abnormal ejaculation has been reported (ejaculation
disorder). This means that the semen does not leave the body
via the urethra, but instead goes into the bladder (retrograde
ejaculation) or the ejaculation volume is reduced or absent
(ejaculation failure). This phenomenon is harmless.
Driving and using machines
There is no information available on whether Flomaxtra XL
affects the ability to drive or to operate machinery or equipment.
However, it is known that Flomaxtra XL may cause drowsiness,
blurred vision, dizziness and fainting. If you suffer from these do

nurse has told you. Check with your doctor, pharmacist or nurse

forgotten to take it earlier. If you have missed a day, just
